Migration of Bar-Tailed Godwits

The bar-tailed godwit has been in the news because of its incredible migration, e.g., “Birds Fly More Than 7,000 Miles Nonstop, Study Shows: In Its Annual Fall Migration, One Godwit Traveled From Alaska to New Zealand in Eight Days” and “Avian Airlines: Alaska to New Zealand Nonstop.”

General works about bird migration are classed in 598.1568 Migration of birds (built with 598 Aves plus 1 General topics of natural history of animals from add table under 592–599 Specific taxonomic groups of animals, following footnote instruction at 598 and instruction at 592–599, plus 568 from 591.568 Migration, following instruction under 1 in add table under 592–599).  Examples of works classed in 598.1568 are Avian Migration and Bird Migration: A General Survey.

A work about migration of a specific kind of bird is classed with the kind of bird, as instructed at 591 Specific topics in natural history of animals: “Class a specific topic in natural history of animals with respect to a specific taxonomic group of animals with the group of animals, plus notation 1 from table under 592-599, e.g., beneficial mammals 599.163.”  The bar-tailed godwit (Limosa lapponica) belongs to the family Scolopacidae, information that can be found in many sources, including Encyclopædia Britannica.  In DDC, the family Scolopacidae is listed in the including note at 598.33 Charadriiformes.  Thus the work Bar-Tailed Godwit: Limosa Lapponica is classed in 598.33.  A work focusing on the migration of the bar-tailed godwit is also classed in 598.33; no further addition is possible because the bar-tailed godwit is in standing room in 598.33 Charadriiformes.
